Want to save time and energy, and still get a home-cooked meal in minutes at home? Try using a pressure cooker. This airtight cooking pot uses steam pressure to cook food very quickly. Unlike a microwave, which can give varied results, a pressure cooker uses about 70 percent less time and energy than conventional cooking but still delivers delicious results. It's also foolproof: Just dump ingredients inside to make stews, chili, breads, desserts and even roast a whole organic chicken.
